I thought I was ordering this battery through Amazon, but in fact the supplier, after telephone discussions about the specifications, invoiced me outside of Amazon's transaction system without being clear that this was happening. The battery arrived reasonably on time but the polarity (positive and negative) markings on the battery base had been scratched out so it was not possible to see exactly which way round the polarity was. Polarity is very important because attaching it to the e-bike's controller the wrong way round would burn out the controller and motor. It transpired after further phone discussions that the battery was a bad fit for my e-bike so under my distance selling rights I rejected it for a full refund. The seller's courier, Parcel2Go, failed to pick the package up two days in succession despite having a tracking number and me waiting in all day for two days. I then elected to take the package to a "drop off" point specified by the seller and a receipt and tracking number was received.
Now, two weeks after attempting to return the package, it apparently has still not been received back by the seller, who has refused my refund despite several requests. I consider two weeks to be ample time for the seller's courier to deliver the return which only had to travel 50 miles. I have now had to contact my bank, and will contact Amazon, in order to recoup my payment. While this seller was polite on the phone, Erolling has failed me as has their courier, Parcel2Go, whose service is appalling. My advice to any buyers of Erolling products is to refuse a transaction that involves Parcel2Go or their associated companies. Erolling has also violated the Sale Of Goods Act and its obligations under distance selling regulations in failing to refund me in a timely manner. I am still waiting for my refund.
